8000 B.C. to 7000 B.C.

The Plano culture of prehistoric Native American people followed the Clovis culture from around 8000 to 7000 B.C. Following the extinction of Ice Age big game animals, the Paleoindians had to change their way of life. They continued to hunt animals, but they focused on bison on the Plains and deer and elk in the eastern forests. The hallmark of the Plano culture is a variety of new kinds of spear points. Plano spear points are different from Clovis points in that they lack the groove, or flute, that characterizes Clovis points.
